New generalized fuzzy metrics and fixed point theorem in fuzzy metric space
(Springer, 2014-12-08)
In this paper, in fuzzy metric spaces (in the sense of Kramosil and Michalek (Kibernetika 11:336-344, 1957)) we introduce the concept of a generalized fuzzy metric which is the extension of a fuzzy metric. First, inspired ...
On best proximity points for set-valued contractions of Nadler type with respect to b-generalized pseudodistances in b-metric spaces
(Springer, 2014-02-14)
In this paper, in b-metric space, we introduce the concept of b-generalized
pseudodistance which is an extension of the b-metric. Next, inspired by the ideas of
Nadler (Pac. J. Math. 30:475-488, 1969) and Abkar and Gabeleh ...
Dynamic Processes, Fixed Points, Endpoints, Asymmetric Structures, and Investigations Related to Caristi, Nadler, and Banach in Uniform Spaces
(Hindawi Publishing Corporation, 2015)
In uniform spaces (...) with symmetric structures determined by the D-families of pseudometrics which define uniformity in
these spaces, the new symmetric and asymmetric structures determined by the J-families of generalized ...
Best Proximity Point Theorem in Quasi-Pseudometric Spaces
(Hindawi, 2016)
In quasi-pseudometric spaces (not necessarily sequentially complete), we continue the research on the quasi-generalized pseudodistances. We introduce the concepts of semiquasiclosed map and contraction of Nadler type with ...
Stability of Nonlinear Dirichlet BVPs Governed by Fractional Laplacian
(Hindawi Publishing Corporation, 2014-03-02)
We consider a class of partial differential equations with the fractional Laplacian and the homogeneous Dirichlet boundary data. Some sufficient condition under which the solutions of the equations considered depend ...
On the existence of an optimal solution of the Mayer problem governed by 2D continuous counterpart of the Fornasini-Marchesini model
(Springer US, 2012-10-23)
In the paper the optimization problem described by some nonlinear hyperbolic
equation being continuous counterpart of the Fornasini-Marchesini model is considered. A
theorem on the existence of at least one solution to ...
Dynamic programming approach to structural optimization problem – numerical algorithm
(AGH University of Science and Technology Press, 2014)
In this paper a new shape optimization algorithm is presented. As a model application we consider state problems related to fluid mechanics, namely the Navier-Stokes equations for viscous incompressible fluids. The general ...
Variational Methods for a Fractional Dirichlet Problem Involving Jumarie’s Derivative
(Hindawi Publishing Corporation, 2015-07-08)
We investigate a fractional Dirichlet problem involving Jumarie’s derivative. Using some variational methods a theorem on the
existence and uniqueness of a solution to such problem is proved. In the proof of the main ...
The Łojasiewicz exponent over a field of arbitrary characteristic
(Springer Verlag, 2015-01-13)
Let K be an algebraically closed field and let K((XQ)) denote the field
of generalized series with coefficients in K. We propose definitions of the local
Łojasiewicz exponent of F = ( f1, . . . , fm) ∈ K[[X, Y ]]m as ...
On conformal submersions with geodesic or minimal fibers
(Springer, 2020)
We prove that every conformal submersion from a round sphere onto an Einstein manifold
with fbers being geodesics is—up to an isometry—the Hopf fbration composed with a
conformal difeomorphism of the complex projective ...
